A grand jury Tuesday handed up an indictment for a Boston man on 13 counts for allegedly raping an Oak Bluffs woman on May 28 in Chilmark.

Bryant K. Brown, 33, of Boston, was indicted on three counts of rape, three counts of assault with intent to rape, one count of indecent assault and battery on a person over 14, five counts of assault and battery on a disabled person, and one count of threat to commit a crime.

Mr. Brown was arraigned in Edgartown District Court on May 29 for allegedly assaulting a 28-year-old disabled woman. Bail was set at $300,000.

According to a Chilmark police statement at the time, the alleged victim met Mr. Brown and his girlfriend in Oak Bluffs. Mr. Brown offered the alleged victim a ride in his Corvette, Cape and Islands assistant district attorney Laura Marshard said. He allegedly took her to the couple’s rental cottage at the Menemsha Inn and assaulted her after his girlfriend had “passed out.”

The alleged victim was held against her will, police said, and called the West Tisbury police at 5:30 a.m. the next day when she escaped from the cottage and was walking on North Road.

The grand jury also issued an indictment for an Edgartown man for trafficking cocaine.

James K. Rowell 2nd, 52, was indicted for trafficking between 28 and 100 grams of cocaine on April 27.

According to the police report filed in court at the time, a confidential source told police Mr. Rowell would be arriving on the Island with a significant amount of cocaine.

Officers reportedly found that Mr. Rowell had 56 grams of cocaine in a surgical glove inside a partially open bag of Dunkin’ Donuts coffee grounds. Without being cut, the cocaine would have a street value of $5,600, the report said.
